We look at the division of 859805 by 86 
We want to figure out the number of times 859805 can be divided by 86.

On to step 1:
86 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 86

Step 2:
The number 86 fits into 85 0 times, leaving a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 86

Moving on to step 3:
86 goes into 859 9 times with a remainder of 85.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 85 after subtracting 774 from 859.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 86

Step 4:
When dividing 858 by 86, we get 9 with a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
The remainder is 84 after subtracting 774 from 858.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 86

Going ahead to step 5:
The number 86 fits into 840 9 times, leaving a remainder of 66.
The next digit of our result is 9. 
Result so far: 999.0
Subtracting 774 from 840 leaves us with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 86

Advancing to step 6:
665 divided by 86 is 7 with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 9997.0
Subtract 602 from 665 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 7:
When dividing 630 by 86, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 9997.7
Subtracting 602 from 630 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
86 can be fit into 280 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 9997.73
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
When dividing 220 by 86, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 9997.732
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 9997.7325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
500 divided by 86 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 9997.73255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 9997.73255, and the remainder is 7e-05.
